In Animation Nodes how can I have an integer value increase from 0 to 100 and back to 0? (0 -> 100 -> 0)
There are two ways to do this, the mathematical way, and the simple method of using an linear mirror interpolation which I will describe here:



In that case, it will start at zero, start increasing till it reach 100 at half the duration, and then start decreasing till it reach zero again at the full duration.
